To all whom it may concern:

Be it known that LCHARLES BRADY KING, a citizen of the United States,residing at Detroit, county of Wayne, State of Michigan, have invented acertain new and useful Improvement in Change-Speed Gears, and declarethe following to be a full, clear, and exact description of the same,such as will enable others skilled in the art to which it pertains tomake and use the same,

reference being had to the accompanying drawings,

izing gear and the casing of the change speed gear showing the containedparts in plan. Fig. 4, is a vertical section of the change speed gearcase, part of the contained mechanism being also shown in section. Fig.5, is a section on the line 5 5 of Fig. 4. Fig. 6, is a detail viewshowing the shifting rod and the. guiding sleeve therefor in section.Fig. 7, is a plan view of the shifting rod looking down upon it in theposition shown in Fig. 6. Fig. 8, is a section of the steering postincluding also the apparatus for operating the steering gear, the changespeed gear and the reversing'gear. Fig. 9, is a detail 'view principallyin section on the line 9-9 of Fig. 8.

A, is the body of an automobile; a, a, are the side pieces of the frame;A, is the front seat and A the backseat. I

A is a rear driving wheel; A the rear axle; A the fly-wheel; A, thetransmission shaft; A", the beveled gear wheel through which motion istransmitted to the beveled gear wheel A of the equalizing gear.

B, is a leyer pivoted. to the free end of a floating lever arm B Thelever B is provided at its upper end with a pedal to be operated by thedriver and adapted at its lower end to operate the clutches between thepower and the driving shaft A. i

B is a connecting rod pivoted at one end to the lever B above the B Theconnecting rod B is provided at its other end with the yoke B inclosingan elongated slot through which slot passes a pin B into an armBlsecured to and adapted to rotate the shaft 13. Upon the ends of theshaft B are lever arms b b, to

l the free ends of which are pivoted t e connecting rods B B whichconnect at B B wit/ thebrake mechanism. 7 i

a The operation of the above described device is as fol-;

lows :The operator presses the upper end of the lever? B forwarddisconnecting the clutch mechanism 13, which may be done withoutactuating the brake, inasmuch as the slot in the yoke B affords lostmotion for this purpose. A further forward movement of the pedal uponthe lever B actuates the brakes and stops the vehicle. I have designatedcollectively the mechanism adjacent to the steering sleeve by thereference letter O, and will call it the steering post.

The steering post 0 consists principally of three concentric slceves,the outer one actuating thereversing mechanism; the next, the changespeed gear and the inner one the steering gear. Specifically C, is thesteering wheel, the hub C of which is secured to the upper end of asleeve 0 The lower end of said sleeve extendsinto the casing 0 C is abeveled gear wheel secured upon the lower end of the sleeve C andmeshing with a sector, or

toothed arc, C of a beveled gear wheel which is secured upon a shaft Cwithin the casing 0 Upon the other end of the shaft C is the arm 0,which is connected in the usual way by a connecting rod C, with thesteering mechanism, not shown.

D, is a handle normally extending laterally to the vehicle and clampedor otherwise secured to the upper end of a sleeve D surrounding thesleeve C and extending downward into the casing C D is a beveled gearwheel, within the casing 0 secured to the lower end of the sleeve D andmeshing with the teeth of the sector or toothed are D of a beveled gearwheel upon one end of a shaft D The shaft 1) at its other end rests in abearing upon one of the side pieces a of the frame.

D is aspur gear wheel upon the shaft D, inclosed within the casing D. V

d, is a rod adapted to slide longitudinally in ways in the casing D,'andto rotate in said ways. Intermediate of its ends, the rod d is providedwith gear teeth d which preferably extend around said rod. The gearteeth d mesh with the gear teeth of the spur gear teeth D as shown mostdistinctly in Fig. 9. The engagement of the teeth d with the teethof'the spur gear wheel D is such as to permit of a rotation of the rod(1.

d is a longitudinally extending slot cut in the rod d. j

d, is a lever arm surrounding the rod (1 and having a key'extending intothe groove or'slot d d is an annular projection around the hub of, thelever arm d v d, is a hook secured to the casing D and extending overand engaging the lugd so that the lever arm d may turn relative to thecasing D, but may not move in the direction of the length of the rod (1.

The outer end of the rod d is connected by a connecting rod d with thegear shifting rod f (Fig. 2).

E, is a handle extending from the side of the gear post C opposite tothe handle D and normally in a direcr sleeve extending from the casingF. One end of said in Fig. 4.

tion lateral to the vehicle and having its hub E clamped or otherwisesecured to a sleeve 15-, surrounding the sleeve 1), and provided a t itslower end with a' lever arm E the hub ll" of which is secured fast tosaid sleeve.

E (Fig. 2) is a connecting rod pivoted at one end to the outer end ofthe lever arm E and at the other end to fllc outer end of the lever armso that; when the handle E'is turned, the lever arm d is actuatedthereby, through the sleeve E arm E and connecting rod E to rotate therod (1 which is so connected to the gear shifting rod f that the latterwill rotate with it. The annular form of the teeth (1 permits of therotation of the rod 11, without effecting their engagement with theteeth of the spur gear wheel T).

F, is the casing of the change speed gear.

F is a stub shaft bearing into a cylindrical aperture formed at the endof the driving shaft A', revolub le independently of said shaft andhaving formed thereon, or rigidly secured thereto, the beveled gearwheel A F'-, is a spur gear wheel secured to the beveled gear wheel Aand having exterior spur gear teeth and interior spur gear teethindicated by the reference letter F F is a counter shaft extendingparallel to the shaft A within the gear casing F and revoluble inbearings in said casing.

F is a spur gear wheel upon the shaft F at one end of said shaft. F asmaller spur gear wheel upon the shaft F at the other end thereof, theteeth of which mesh with the exterior teeth of the spur gear wheel F-.

F is a spur gear wheelupon the shaft F intermediate in size and positionbetween the spur gear wheels F and F f, is a sleeve within the casing F,adapted to slide longitudinally upon the shaft A and'provided with a keyextending into a key way f B (Fig. 3),"orgroove upon the shaft A, sothat said sleeve is restrained from angular movement relative to saidshaft.

f is a spur gear wheel upon the sleeve f adapted to engage with the spurgear wheel F when the sleeve F is moved into a position that brings saidspur gear wheels opposite each other.

f is a spur gear wheel, upon the sleeve f, of such a diameter that itwill engage with the spur gee: wheel F when the sleeve f is moved to aposition bringing said spur gear wheels opposite each other. The teethof the spur gear wheel f are also adapted to engage the interior gearteeth F of the spur gear wheel F when the sleeve f is pushed to that endof its travel.

G, is a lever arm surrounding, at one end, the rod j and having a keyextending into a longitudinal key way, or slot, in said rod so that saidrod may move longitudinally with reference to said swinging arm, but anyrotation of said rod will turn said lever arm. The hub of said lever armabuts against the end of the gear case F at one side and against 2. lugGr (Fig. 3) at the other side, so that a linear movement of saidswinging arm relative to the gear case F is restrained.

The rod j is provided with a key way above spoken of, extending for aconsiderable distance longitudinally thereto and 'is adapted to slidelongitudinally in a rod being within the casing F and the otherextending is a groove branching at right angles to the groove 7 or keyway f 5 opposite the depression 2 and communicating with the. latter.

f, is a pin pressed inward by the spring f and extending into the grooveor key wayf in the rodf. The pin f enters the depressions l, 2, 3, 4 and5, and by'the friction caused thereby marks the-different positions ofthe gear shifting rod f Said pin prevents the rotation of the rod frelative to the-gear casing F, except at the position marked by thedepression 2 at which position the rod f, may be rotated carrying thepin f" into the groove f".

The operation of the above described device is as follows z-Tho wheel C(Fig. 8) is rotated carrying with it, the beveled gear wheel (3,actuating the sector (3 the shaft (3, and arm 0, and turning thesteering wheels through the connecting rod 7" and the usual mechanism,not shown. The handle D is turned carrying with it the beveled-gearwheel D sector D shaft D, spur gear wheel D which actuates through theteeth (1, the rod 1! which carries with it through the connecting rod d,the gear shifting rod f. Therod f carries with it the sleeve f by meansof a fork f upon the inner end of the rod f engaging the sleeve f. Whenthe handle D is so moved as to draw the rod 11 and with it the rod f tothe end of the travel toward the front of the vehicle, the sleeve f ismoved so to engage the spur gear wheel f with the spur gear wheel F", sothat the shaft A actuates the counter shaft F? throughsaid spur gearwheels and the beveledsp ur gear wheel A through the spur gear wheels Fand F thus giving the slow motion ahead. When the handle D is so movedas to carry the rod f to the position in which'the pinf engages in thedepression 2, the sleeve f is entirely disengaged from the shaft F andthe shaft A may rotate without moving the vehicle. The pin f is thenopposite the slot or groove f. If, now, the handle E is turned, it willturn the rod (1 through the arms E (1 and the turning of the rod d willturn the rod f bring iug the pin f into the slot f and turning theswinging arm G so as to engage the wheel G with the spur gear wheels f land F The revolutions of the shaft-A will then communicate and reversethe movement of the beveled gear wheel A and drive the vehicle backward.If now, the handle E is moved to its first position, the pin f isbrought back into the groove or key way f and the wheel G is disengagedfrom the wheels f l and F and the shaft A is again free to turn withoutactuating the rest of the mechanism. If now, the handle D is turnedfurther, it will move the rods d and f further; the rod j carrying withit the sleeve f and causing the spur gear wheel f to engage with thespur gear wheel F thus securing the intermediate speed ahead. When therod f is moved still further, the spur gear wheel] disengages from thespur gear wheel F and engages directly with the interior teeth F of thespur gear wheel F thus binding the shaft A directly to the shaft F andcommunicating the fast speed ahead to the vehicle.

Inasmuch as a' slight angular rotation of the rods (1 and f issuflicient to adjust the reverse gearing, any
